The resource files on this page are in the following formats:
For documents with text and graphics there are Word files and pdf files (read with Adobe Acrobat, the free downloadable program available at www.adobe.com).
For music there are Sibelius files playable with the plug-in Scorch. Go to the Scorch webpage at Sibelius Music and follow the directions there to configure your computer to access and playback Scorch files.
If you can view a Scorch file, you can also print the score directly from that page (i.e., it doesn't have to be saved in pdf format first). Just use the print button on the Scorch toolbar.
